Step 11: Go over the lines with a pen or marker to make your cartoon Tyrannosaurus rex drawing permanent. Take your time and be careful when you ink to avoid any accidents. After the ink dries, get rid of every pencil mark with an eraser.
Final Step: Color your cartoon dinosaur drawing any way you'd like, using color pencils markers or crayons! For this look, draw thin, curved shapes using dark green on the head, body and leg for stripes. Using light green, draw an outline below the eye, and on the bottom of the head and body. Color the inside. Use yellow for the lower half of the T. rex's head, body and tail. Use dark and light brown for the eye. Don't forget to pause the video to draw at your own pace.
